STEAM-TRAP.

Specification of Letters Patent.

Patented Dec. 4, 1906.

Application filed July 18, 1.906. Serial No. 326,657.

' amount of water of condensation thatois returned through the trap.

A further object of the invention is to provide means for preventing such water of-condensation from escaping into the outlet from the trap-reservoir from its supply-pipe Without having first passed into the reservoir, and thereby been measured.

t is also an object of the invention to pro vide in connection with a steam-trap for'returning water of condensation to the boiler improved means for controlling the inlet and outlet passages to the steam-trap, whereby back pressure or live steam from the boiler will be prevented from escaping through the outlet-pipe of the reservoir that leads into the boi er.

In the accompanying drawings, representing an embodiment of my invention Figure 1 shows the device in side elevation with the steam-trap in the filling position: Fig. 2 is a similar view, but with the trap or receiver in its lowered position and the regulating-valves correspondingly shifted. Fig. 3 shows in end elevation, partly in section, the admission and the discharge passages for the re ceiver. Fig. 4 is an end elevation of the parts shown in Fig. 1'. Fig. 5 is a longitudinal section through the controlling-valves.

Fig. 6 is a view similar to Fig. 5, but with the.

valves and lever in another .position. Fig. 7 is a vertical sectional view, partly in elevation, through the receiver and certain controlling-valves therefor and Fig. 8 is a section on the lineS 8 indicated in Fig. 3, showing a portion of the receiver.

While the present invention is applicable to any form of steam-trap that is lowered when containing a certain amount of water of condensation and then elevated after such water has been discharged, the invention is illustrated as aipplied to a form of steam-trap patented by rank A. Littlefield on February 7, 1893, No. 4:1,486, and also patented end, preferably adjustable thereon.

to the same inventor on No. 513,648;

In the construction shown there is a receiving vessel 12, suitably supported to be January 30,1894,

raised and lowered. When the receiver is elevated, it is connected to receive water of condensation until a suitable weight is overbalanced, whereupon the receiver will lower. In the latter position, by suitable automatic valve mechanism, the supply is cut oil and an outlet-passage opened, whereby such water will find exit. Upon the vessel being emptied it will overbalance the weight and rise to its former position. A suitable form of register or meter M is arranged on the frame or base B of the apparatus and connected with the receiver by a rod 13, pivoted to the receiver at 14 and also pivoted to an arm 15, connected with the shaft 16 of the meter. Thereby the shaft of the meter is oscillated at each oscillation of the receiver, and such oscillations are caused to be registered or recorded by the meter M.

In the construction shown a lever 17 is pivoted on a frame member 18 above the receiver l2 and carries a weight 1.9 on its free To the other end of the lever 17 is pivoted. a link 20, that is also pivoted to the receiver at the place 14. At the small end of the receiver is a transverse tubular portion 21, having a trunnion bearing on tubular members 22 and 23, whereby the receiver is supported to oscillate. The latter trunnion members project towardeach other from the upper portion of a U-shaped support The portion 25 of this support is tubular, connecting with the tubular trunnion member 23, and thereby communicating with a tubular portion 26 of the crossnew 21 of the receiver. The chamber 27 does not open directly into the receiver, but is closed except to an inlet-pipe 28, leading into the receiver therefrom and terminating near its upper portion, as shown in Fig. 7. The lower end of the tubular support 22 connects with a valve member 29, to which leads a steam-supply pipe 30. The valve-seat 31 controls the port admitting the steam into the device"through the tubular support 25. The stem 32 of this valve also carries a valve member 33, that controls the admission of atmospheric air through a pipe 34. When the trap is in the u per position, the steam admission is close and the air admission is open, as indicated'iiiFig. 7.

. forced out of the receiverthrou h its proper Outlet.

The trunnion'member 22 is constantly open to the chamber of the receiver and has at its outer end a T member 35, attached thereto, to which are connected the supplypipe and the outlet-pipe for the receiver, as best shown in l 5 and 8. In these two.

' pipes are placed suitable valves, and mechthe inlet-pipe closed.

anism connects these valves with the receiver, whereby when the receiver is in the elevated position tor the admission of water of condensation the supply-pipe valve will be opened and the outlet-pipe valve closed; but upon the receiver filling and assuming its lower position for discharge the valve in the outlet-pipe will be opened and the valve in The outlet-pipe is usually connected with a steam-boiler, and therefore is open to full boiler-pressure; but at this stage the receiver is open to full boilerpressure through the valve member 29 and pipe 28, leading into the receiver. In the construction shown a 'supplypipe 36 is con:

nected with the T tand provided with a valve member 37, in the form shown being a balanced valve. An outlet-pipe extends from the T 36 and is shown as provided with a balanced valve 39. on a post 41, that may extend upward from the T 35, and this lever is connected with the stems 42 and 43 ol the valves 37 and 39, respectively. By this means when one valve is in the open position the other valve will be closed, such two positions being indicated in Figs. 5 and 6, respectively. This lever extends along the side of the receiver 12 andprojects through a slot 44 in an arm 45, seoured to the receiver. This slot is so arranged that when the receiver reaches the limit of its upper position the bottom wall of the slot will engage the lever {l0 and move the lever to close the valve 39 in the outlet- .pipe and at the same time open the valve 37 1n the inlet-pipe, as shown in Fig. 5; will permit admission of the water of condensation through the valve 37 and through the T 36 and trunnion-pipe .32, as indicated by the arrows in Fig. 5; but when the receiver becomes filled and is lowered by the weight of the water the upper wall of the slot in the arm 45 will strike thelever 40 at the limit of 'the' lowering movement, and thereby shift the lever to close the valve 37 in the supplypipe and open the valve 39 in theoutle-t-pipe. At this osition of the receiver the live-steam supply as been admitted into the receiver through the pipe 28 at the same time that the boilcr-pressure is in communication with the water through the outlet-pipe -.38 and A lever 40 is pivoted.

valve 38 By this arrangtzxient the water will be practicallybalanced, and therefore can flow out of the receiver by gravity through the outlet-pipe 3S and the valve 39, as indicated by the arrows in Fig. 6. v I

From this arrangement it follows that when the r ceiver is in the filling position no water can escape into the outlet-pipe and to the boiler-pipe. The valve 39 is closed,

" therefore, and all of the water of condensather seen that the controllingvalves in the supply and outlet pipes being operated by the receiver will be of great advantage to prevent any escape of live steam from back pressure through the outlet-pipe by reason of the valve 39.
